Metal building insulation in Texas climate

[gearheads78]

What should I do? I am about out of money building my new building so I need to either do a little at a time or find a way to save some money.
I don't plan on doing A/C any time soon if ever but I would like to insulate to keep the heat from building up inside as much as possible.

My builder and a few people I talk to say spray foam but its super expensive. I have also been told that its not fire retardent and needs to be covered by drywall which I didn't intend on doing. Since I am always creating a lot of sparks or welding is this a problem with the spray foam?

I was thinking maybe do the spray foam on the roof now and do the board type with foil on the walls as I can afford it?

What have you done and what do you wish you did different?

In Texas, I would prolly just go with some EPS between the studs and a foil faced 1/2" over the studs on top of it. That will "help" with the sparks. It will also kill the condensation that will be dripping from the ceiling in the spring and fall. Just put some hard board or metal or something where any sparks will be constantly flying.

I used the foil covered foam insulation. In the walls the foil faces out into the cavities. On the roof the foil faces in. It is amazing to me how well it insulates my shop from the summer heat and my shop has a dark brown roof steel roof. The other thing that helps keep my shop cool is that it has continuous ridge and soffit vents.

So its better to use vents then to seal it up with spay foam?

I think that is the case when you are trying to keep the building cool in the summer without air conditioning. I am able to work in my shop just about all summer long and it's not too bad. If it gets much above 100 I pack it in though. My shop also has 12 foot sidewalls so this might play into this.
